Environment: milieu / climate zone / depth range / distribution range
Ecology
Marine; brackish; pelagic-neritic; depth range 0 - 50 m (Ref. 189). Subtropical; 36°N - 20°N, 121°W - 110°W (Ref. 189)
Eastern Central Pacific: Morro Bay, California (Ref. 2850) to Magdalena Bay, Baja California, Mexico.
Size / Weight / Age
Maturity: Lm ? range ? - ? cm
Max length : 13.3 cm SL male/unsexed; (Ref. 9298); common length : 10.0 cm SL male/unsexed; (Ref. 9298); max. reported age: 6 years (Ref. 72482)
Dorsal spines (total): 0; Anal spines: 0; Anal soft rays: 27 - 34. Moderately deep. Snout pointed, about 1/2 to 3/4 eye diameter; maxilla moderate, tip rather blunt, not reaching to hind border of pre-operculum; pseudobranch short, covered by skin; gill cover canals of panamensis-type. Anal fin origin a little before midpoint of dorsal fin base. A bright silver stripe along flank, often as wide as eye, not fading on preservation.
A schooling species most commonly found in bays and inlets (the fourth most abundant fish taken by various gear in Newport Bay, California; its eggs are the most abundant of 7 species sampled, especially in May). The ovarian eggs are spherical. Eggs and larvae are planktonic (Ref. 35602). Feeds on plankton (Ref. 8593). Basically filter-feeders, but at times have been observed feeding by selection (Ref. 4930). Normally used as bait (Ref. 9298).

50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00513 (0.00232 - 0.01135), b=3.14 (2.96 - 3.32), in cm total length, based on LWR estimates for this Genus-body shape (Ref.

Trophic level (Ref.
69278): 3.4 ±0.45 se; based on food items.
Resilience (Ref.
120179): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
